Depends on your conditions for failure. If you are simply looking to
get around hardware failures or other physical conditions which result
in the T1s going down, you can use a reliable piece of ISDN gateway
equipment in front of the Asterisk boxes that pushes SIP out the other
end and configure it to fail over calls to a second VoIP peer. It
creates a single point of failure, but one which is far, far more
unlikely to fail than PC hardware.
Or, you can use a DS1-level DACS that can protection switch the T1s to
another port.
Ultimately, your failover options are limited if you have T1s physically
going into an Asterisk box with a T1 card. Your best bet is to somehow
separate the two components; then, you can get the proper redundancy
measures implemented on both sides in ways that are most native and
technologically appropriate, instead of coupling them in a way that
makes them difficult to divest.
